Here are some of the things that I use on a weekly basis. I have found it easier to 'package' my lessons in plastic crates as this then allows for me to have these resources organised according to the lesson content.
You would need to gather some materials for using with Makey Makey, micro:bits and other electronic projects...
Conductive materials (Aluminum foil, aluminum or copper tape, wire, PlayDoh)
Spare wood / cardboard and plastic tubing
Tape or glue
Scissors or craft knives
Wire cutters and/or pliers
